The stamps used on this card came from Hero Arts Clear Design. I bought the letter "B" set from the line to try out and see how I liked it. They stamp wonderfully (really the best of anything I have used thus far with clear stamps). I used my regular SU classic ink and had no smudging from the image. I am definitely going to buy more of these when I see a deal, they are really good quality clear stamps. Have a great day!
